Abstract:
A resin composition, a printed circuit board using the composition, and a method of manufacturing the printed circuit board. The resin composition includes: a photopolymerizable compound, such as one having an ethylenically unsaturated bond which is polymerizable in a molecule, a photoinitiator, and a surface-modified silica by an alkyl sulfonated tetrazole compound.
Abstract:
Disclosed herein are a composite material including an anisotropic filler and a component having directionality, wherein the component having directionality has a length in a range of 1.5 to 20 based on a length of the anisotropic filler, a method for preparing thereof, and a substrate using the same as an insulation layer. According to the exemplary embodiment of the present invention, in the composite material using the anisotropic filler, the component having directionality is used for controlling the dispersion directionality of the anisotropic filler, whereby at the time of orientation of the component having directionality, the directionality in which the anisotropic filler is dispersed may be controlled to improve the dispersion of the anisotropic filler.
Abstract:
An isoflavone-based polymer, a lens containing the isoflavone-based polymer, and a camera module including the lens are provided. The isoflavone-based polymer includes an isoflavone-based skeleton in a main chain thereof, and includes at least one linking group selected from the group consisting of an ester group and a carbonate group. Whereby, the isoflavone-based polymer exhibits excellent optical properties.
